Adding Custom Texts

You can add custom sacred texts to the chatbot in several ways:

2. Directly in the data folder: Add JSON files with the following structure:

   [
     {
       "chapter": 1,
       "verse": 1,
       "text": "The verse text goes here",
       "keywords": ["keyword1", "keyword2"]
     }
   ]

3. Text Format: For plain text files, use the following format:

   Chapter 1
   Verse 1: The verse text goes here
   
   Verse 2: Another verse text
   

4. Markdown Format: For markdown files, use:

   # Chapter 1
   
   ## Verse 1
   The verse text goes here
   
   ## Verse 2
   Another verse text
